the one all the way on the right says +W (woofer) and +MR (midrange, u either use a woofer or a midrange) but there is only a + in front and only one hook. the one to the left says +T (tweeter) again, no - sign and only 1 hook. now, here it gets even more confusing. the two to the left of the tweeter hook says COMMON over them, but nothing else. and finally, the last hook says +IN (for the input to the binding posts). how the hell do i hook these up? i must be missing something. anything helpful would be appreciated!
